My wife humiliated my sick mother, withheld her medication, and threatened to send her to a nursing home if she exposed the truth. But when I came home early and found the hidden prescriptions beneath her bed, my wife revealed that my mother had already signed away a property worth 6.4 million pesos.

With the preventive annotation locked onto the Coyoacán property, the syndicate behind the land-grab began to tear itself apart from within.

Late on a rainy Thursday afternoon, Gabriel and I met with the Lead State Prosecutor, Attorney Javier Ruiz, in his high-security office near the Reforma district. On the desk between us sat three laptop screens displaying financial records, wire transfers, and wiretapped phone conversations provided by federal investigators.

"Notary Héctor Trejo is breaking," Attorney Ruiz informed us, sliding a set of transcripts across the table. "Once we froze his firm's corporate accounts and seized his luxury properties in Polanco, his defense team realized he was facing up to thirty years for organized crime and forgery."

"Is he willing to turn state's evidence against Mónica and Rodrigo?" I asked.

"He already has," Ruiz replied with a sharp, victorious smile. "Two hours ago, Trejo signed a full confession. He admitted that Rodrigo Salgado paid him eight hundred thousand pesos in cash to forge the public deed. More importantly, he handed over a secret audio recording Mónica made during the day she forced your mother's thumb onto the pad."

Ruiz pressed a key on his computer.

Mónica's sharp, panicked voice filled the office: “Hurry up and stamp it, Héctor! The old woman is burning up with fever and she’s starting to pass out! If Mateo comes home early and sees this, the whole thing falls apart!”

Then came Trejo’s recorded voice: “Is Salgado sure the son doesn't suspect anything about the accounting discrepancies?”

Mónica's cold laugh echoed through the speakers: “Mateo trusts me completely. He thinks I'm an angel taking care of his pathetic mother. He’s too busy working twelve-hour days to pay for her medicines—medicines I’m throwing in the trash anyway.”

Listening to her voice—so cold, so monstrous, so completely devoid of human empathy—made my hands shake with righteous fury.

"This recording seals the charge of premeditated elder abuse, attempted murder by medical deprivation, and organized fraud," Attorney Ruiz said, turning off the audio. "Mónica Flores and Rodrigo Salgado are facing maximum, non-bailable statutory sentences."
